Usain Bolt crossed the finish line and kept running. The world’s fastest man was ready to celebrate, and the guest list for the party included a delirious crowd at Olympic Stadium.

Bolt pulled away from a group of the world’s best sprinters and won the 100-meter dash in 9.63 seconds on Sunday night, joining Carl Lewis as the only men with consecutive gold medals in the marquee track and field event at the Summer Games.

World champion Yohan Blake, Bolt’s training partner and Jamaican countryman, won the silver in 9.75 seconds, and 2004 Olympic champion Justin Gatlin of the U.S. earned the bronze in 9.79 seconds. Everyone in the final broke 10 seconds except Asafa Powell of Jamaica, who pulled up with a groin injury.

“I executed, and that’s the key,” Bolt said. “I stopped worrying about the start. The end is what’s important.”

Bolt celebrated his Olympic-record time with a few high-fives for some front-row fans, a kiss for the track and even a somersault. Thousands in the crowd chanted “Usain! Usain! Usain!”

Also Sunday night, Oscar Pistorius was last in his 400-meter semifinal a day after the double-amputee made his Olympic debut. The South African finished in 46.54 seconds, way slower than his career best of 45.07 and nearly 2 seconds slower than the winner of his heat, world champion Kirani James of Grenada.

James immediately walked over to Pistorius after the race and asked to trade name bibs, to keep as a souvenir. The pair shook hands and hugged.

The champions included American Sanya Richards-Ross (women’s 400 meters), Ethiopia’s Tiki Gelana (women’s marathon), Kazakhstan’s Olga Rypakova (women’s triple jump), Hungary’s Krisztian Pars (men’s hammer throw) and Kenya’s Ezekiel Kemboi (men’s 3,000-meter steeplechase).

“This has just been the experience of a lifetime,” said Richard-Ross, who cried after a disappointing third-place finish in Beijing. “I’ve dreamt about this moment for 20 years.”

Britain picked up two more gold medals after winning six events during a banner Saturday.

Andy Murray cruised past Roger Federer 6-2, 6-1, 6-4 in the men’s singles final at Wimbledon, then added a silver medal in mixed doubles.

Murray avenged a loss to Federer in last month’s Wimbledon final while becoming the first British man to win the gold in singles since Josiah Ritchie in 1908.

Ben Ainslie earned another gold in the Finn class to become the most successful sailor in Olympic history.

After trailing the entire regatta, Ainslie was spot-on with his tactics in the medals race and got a little help from the front of the fleet. He won his fourth straight gold and fifth straight games medal overall, eclipsing Denmark’s Paul Elvstrom, who won four straight gold medals from 1948-60.


Serena Williams added another Olympic title when she teamed with sister Venus to beat Andrea Hlavackova and Lucie Hradecka of the Czech Republic 6-4, 6-4 in the women’s doubles final.

Serena also won the women’s singles tournament and is tennis’ first double gold medalist at an Olympics since Venus won singles and doubles at the 2000 Sydney Games. The sisters also won the doubles gold at the 2008 Beijing Olympics.


Diana Taurasi had 22 points and the U.S. women matched their Olympic scoring record in a 114-66 rout of China.
